Schober Organ Notes No. 66
OVERTURE
Disclaimer: We accept no responsibility for any unfavorable consequences
resulting from following our advice
The provider of the Message Board service of our Web Page went out of
business as of March and as a consequence we no longer have a message board.
Pete Stark our web master is trying to find another (free) provider. Hopefully
he will succeed soon.
For this issue, I have quite a bit of material. Several members have
contributed, and it is too much for one issue, yet too good to cut or shorten,
so I am serializing one article and postponing another. (See below)
THE THREE MANUAL SCHOBER
Our member Captain David Casteel (USAF) sent me a lot of interesting material
about the Schober three manual Recital and Theatre organs which unfortunately
never went into production. He was involved in voicing them to some extent.
Unfortunately I have to postpone this portrait-story until the next issue
of Organ Notes as I have no room in this issue.
RESISTORS and TRANSISTORS
Our member Richard Peterson who is restoring a Theatre Schober wrote the
following: "Received the electrolytics and 2N4403* transistors and started
working on the theater organ. The good news is that the transistors seem
to replace the 046127's* just fine. The waveforms on the oscilloscope appear
to be identical. The bad news is concerning the 30 year old carbon resistors.
About 50 percent of them have increased in value to the point that they
are way out of tolerance (up to 100%). So, back to the vendor for several
hundred resistors. Fortunately, they only cost a penny a piece in lots
of a hundred but the job is now a much longer time frame."
[The 2N4403 is a usable silicon replacement for the germanium Schober
046127 which is used in the majority of Schober organs that were designed
using PNP transistors. It works as a replacement in many applications and
its advantage is that it is quiet. The Schober 046127 is actually a germanium
2N404 marked with a Schober part number. AK]
OSCILLATION PROBLEM IN PEDAL GENERATOR
Richard Peterson had another problem and shared his solution with
us. He originally wrote: "Finished [restoring] the pedal generator board
last night but the input is oscillating so have a bit of work on that one
..." In a subsequent e-mail he wrote: "... and I solved the problem with
the pedal generator with a 120pf capacitor on the input to ground. The
value of the capacitor is so small that it doesn't affect the low frequency
pedal tones."
RECITAL CLAVIER SPRINGS
As many of you know, the original factory-made pedal clavier had flat leaf
springs that broke after a period of use. (The later pedal clavier kit
did not suffer from this problem). Schober came out with a Information
Bulletin/kit, BN-039, which gave instructions for the removal of the leaf
springs and their replacement with coil springs -- 32 each of tight wound
expansion coil springs, screw eyes and #6 x 7/8 round head wood screws
were provided. No mention was made of the size of the screw eyes and, more
unfortunately, the spring size. As a consequence, anyone who has lately
wanted to make this modification by just following the instructions has
had to experiment with springs.
Fortunately, our member Charles Witherell had made this modification
with a BN-039 kit. The carbon steel replacement springs of the kit also
failed after a while. He replaced the Schober replacements with stainless
steel (which last longer) springs of the same size. He sent me a replacement
spring and a spring he now uses, so that I could measure them. The original
measures 0.963" long (without loops), 0.306" O.D. and the wire thickness
is 0.035". Charles now uses another spring because it is easier to find,
not because he prefers it. It has a smaller diameter which makes it a little
harder to fit over the screw eyes, but he writes that it works well. It
measures 0.850" length, 0.237" O.D. and the wire is 0.032" thick. The package
it came in is marked BERG, stock #SPR10-20 (there is also a 418-3133-M
printed on the pack, I don't know what that signifies). Winfred M. Berg,

Organ Interests
Perhaps a word on my background would be helpful in understanding what
led me to buy a Schober organ in the first place. Unfortunately, I do not
have the electronics expertise, or genuine aptitude for it, that I sense
exists among many of your readers. I have had courses in the fundamentals,
own a good many books on the subject, and have various items of test equipment
- many of them prompted by the ownership of the Schober organ. My field
is engineering (B.S. in Mechanical Engineering from Newark College of Engineering
in New Jersey, with graduate study in metallurgy, materials science and
law). I have worked largely in the field of metallurgical research and
development, and did so for nearly 30 years in the New York/ New Jersey
metropolitan area.
When increasing commuter traffic and a growing intolerance for the lousy
weather in the region finally got to us, we moved to California where I
have worked in generally the same field for the University of California's
Lawrence Livermore National Laboratory, retiring from there in 1990. We
moved to the Monterey area from the San Francisco Bay area in 1992 where
we have 3 acres surrounded by rolling hills - a pleasant contrast to the
increasingly crowded urban sprawl of the Bay Area fed largely by the growing
computer industry. I continue working in the engineering field with a consulting
business here in the Monterey area, concentrating mostly on failure analysis
and forensic metallurgy associated with product litigation.
My attraction and love for organ music, and music in general, began
at an early age - probably through listening to church music. My parents
attended every church affair there was and never used baby-sitters; so
if the lights were on at the church, we were all there. I was fascinated
with the sound and rumbling of the beautiful pipe organ there. When I got
a job as a welder and machinist during WWII in a "war plant" I became acquainted
with a co-worker who also shared an interest in and appreciation for organ
music. He knew a lady who had several old foot-powered reed organs in an
old barn in New Jersey. They were all for sale and I ended up buying one
of them - a Wilcox and White organ with a natural oak console. The organ
looked great, but its bellows were shot and its other innards had seen
better days.
Without any expertise at all, and being a teenager to boot, I attempted
to bypass the worn-out bellows with a jury-rigged connection using Johnson
& Johnson adhesive tape to my mother's old Electrolux vacuum cleaner.
This gave a mediocre vacuum, not nearly enough to make the reeds sound
as they should have, and there were other leaks throughout the organ. The
net effect of these attempts was a high level of personal frustration over
being unable to get any decent level of sound from the thing and spending
some 90% of my spare time trying to repair/restore the bellows and other
faulty components. But an occasional brief period when I could make it
through a short number without a serious air leak or other pneumatic/mechanical
problem was sufficiently rewarding to keep me from sending the organ to
the dumper sooner than I did.
My fascination with the organ persisted though, and took on even more
exciting dimensions a few years later when our church hired a new organist
- a 19 year-old organist who was not only the most gorgeous girl I had
ever seen but - even at that young age - was an accomplished master of
the pipe organ! She was able to get the grandest sounds out of that 1920s
Moller in our church that nobody ever realized had been hidden within that
box of pipes. We became very good friends, even though I was
a few years younger, and a few years later she became my wife. We celebrated
our 50th wedding anniversary last November.
For various reasons, a few years before we were married in late 1950,
we left that church in the city with the old Moller organ. Also about that
time, I was called to serve in the Korean War and spent 19 months overseas
with the U.S. Army Engineers in Korea (1951-1952). On Sundays, I played
an old GI field organ for our battalion's church services, as well as for
several Armed Forces Radio Service programs during the week that were broadcast
to the troops throughout Korea.
Before my military service, however, and before we were married, we
pooled our meager financial resources and purchased a new Hammond (C? Model)
electric organ, which just barely fit into the narrow living room of the
house where my wife-to-be lived in Jersey City. The Hammond served well
as a practice instrument for my wife while I was away in the service and
in between church organist jobs in and around the area. Although we moved
out of the city upon my graduation from engineering school in the late
1950s, we kept the Hammond up and running and both played it frequently."

Recital Organ Block Diagram
Member Max Cannon drew up a great block diagram for the Recital. Pete Stark
drew one for the Theatre quite a while ago and included it in his Tech
Notes #6. Anyone wanting a copy of either, send me a SASE. (see address,

Wanted
Wurlitzer Electrostatic Organ of the type manufactured in the 1950's and
early 1960's. This organ had a bank of 73 or 85 reeds all blowing simultaneously
in a soundproof enclosure. Individual tones are formed capacitatively by
keying a polarizing voltage to one or more pickups associated with each
reed. I would prefer a console with 25 or preferably 32 pedals, but would
consider a spinet also. Please note that I am specifically not interested
in the earlier style of Wurlitzer electrostatic reed organs in which the
individual reeds were sounded by a pallet-valve system. If you have any
information on such an instrument, send it to Eric C. Larson: E-mail: ericlarsonco@aol.com
Information Wanted
Larry Blyly writes: Our local high school has a fight song entitled "Side
by Side and Stepping High." (If I knew how I would put in a bar or two
of the music.) It was introduced in the late 1930s. A dispute has developed
over the origin of the lyrics. Certain individuals claim they helped write
them. I dispute it, because the words are entirely "generic." I really
don't know how to pursue finding the real origin of the music and words.
Doing a "search" we found a Texas high school with the same lyrics on their
website. The website is now closed but the music is still shown at: columbuscardinals.tripod.com/fight.html
They don't know the origin either. At this time only hand written "parts"
are existing. Perhaps you could insert a query in the newsletter. Someone
out there might have heard the song at still another school. Or perhaps
someone can help us determine how to find the origin. Just a trivial project,
but isn't that what orphan-organ owners are interested in? Hartford, MI,
